Failed to interpret '%level_value' conversion word #1016

Closed thedevd closed 5 months ago

Describe the bug Using logLevelValue (field name level_value) in logback throws Failed to interpret '%level_value' conversion word

To Reproduce Steps to reproduce the behavior:

  1. Use this encoder in logback.xml configuration...

    <encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">
        <providers>
            <timestamp>
                <pattern>yyyy-MM-dd'T'HH:mm:ss.SSS'Z'</pattern>
                <timeZone>UTC</timeZone>
                <fieldName>timestamp</fieldName>
            </timestamp>
            <pattern>
                <omitEmptyFields>true</omitEmptyFields>
                <pattern>
                    {
                    "level": "%level",
                    "log_level": "%level_value",
                    "logger": "%logger",
                    "msg": "%message",
                    "trace_id": "%mdc{traceId}"
                    }
                </pattern>
            </pattern>
        </providers>
    </encoder>

  2. See error, or unexpected output

**Expected behavior**
Although the documentation here https://github.com/logfellow/logstash-logback-encoder?tab=readme-ov-file#providers-for-loggingevents says use field name level_value for Logger level numerical value, but it does not work

* what output did you expect

**Additional context**
Following is the version information

* logstash-logback-encoder 7.4
`"net.logstash.logback" % "logstash-logback-encoder" % "7.4"`
* logback version - 1.4.11
* jackson version - 2.17.0
* java version - 11.0.22
* play framework - 3.0.0

Oops sorry for incovenience, I think I have to add under to include level_value for numerical log value, however I do not want it to that long I mean 20000 for INFO (I want simply 2)
